Opening weekend is typically an opportunity for the makers of a movie to celebrate or mourn, depending how the box office returns look. For Kevin Hart, it was another chance to hustle.

After the stand-up comedian’s concert film “Let Me Explain” opened nation-wide last Wednesday, Mr. Hart spent the holiday weekend dropping in at screenings in cities like Dallas, Philadelphia, and Washington, DC. In between frequent retweets from fans who loved his movie, Mr. Hart announced he’d be buying popcorn and tickets at the theaters he visited.

Kevin Hart is arguably the world’s most popular stand-up comedian and a fast rising Hollywood star with four movies set to come out next year. But he prides himself on a direct relationship with fans, including marketing to his seven million-plus Twitter and Facebook fans.

Not coincidentally, that’s a large part of his appeal to the companies he’s working with, including “Let Me Explain” distributor Lionsgate.

“Now the movies are coming and the only reason why is they see I have a fan base,” said Mr. Hart, whose stand-up performance have sold out Madison Square Garden in New York and the O2 Arena in London.

With more than $17 million in ticket sales, “Let Me Explain” is already the fifth highest grossing stand-up movie of all time and on its way to the top three, behind only Eddie Murphy’s “Raw” and possibly “The Original Kings of Comedy,” which featured Steve Harvey, D.L. Hughley, Bernie Mac and Cedric the Entertainer.

But Mr. Hart doesn’t see it as an opportunity to focus on a movie career. Though his schedule is packed with one film after another, the 32 year-old father of two is producing a second season of “Real Husbands of Hollywood” for BET and said he hopes to start work on a new stand-up tour by the end of this year.

“Now I’m getting the fruits of all my labor and it’s a great feeling, but I’m not comfortable,” Mr. Hart said. “It makes me want to work harder and achieve more — acting, writing, directing, producing, funding. There are so many things I can do now. It’s not a time to be comfortable and slow down.”
